【问题】

I have a text file which has all the information I need in lines and this needs to be converted into a .csv file.

Example:

abbccccdeffffiiiiiiiiiiiiiijjkkkkkkkkkkkllmmmmmmnnooo
abbccccdeffffiiiiiiiiiiiiiijjkkkkkkkkkkkllmmmmmmnnooo
abbccccdeffffiiiiiiiiiiiiiijjkkkkkkkkkkkllmmmmmmnnooo
abbccccdeffffiiiiiiiiiiiiiijjkkkkkkkkkkkllmmmmmmnnooo
abbccccdeffffiiiiiiiiiiiiiijjkkkkkkkkkkkllmmmmmmnnooo
abbccccdeffffiiiiiiiiiiiiiijjkkkkkkkkkkkllmmmmmmnnooo

So basically

• 1.“a” is first column with just one char
• 2.“bb” is second column with length 2
• 3.“cccc” is third column with length 4
• 4.“d” is fourth column with length 1
• 5.“e” is fifth column with length 1
• 6.“ffff” is sixth column with length 4

As we can see from this example, I cannot use a delimiter with space or commas, they are all of different lengths. Please point me to the right direction. I just need an idea of how to approach to this problem.

按列取记录可用SPL实现，代码简单易懂：

A1：读取source.csv文件内容。

A2：使用mid(s, start{, len})函数获取字符串的子串     ，以便把A1每一行拆分成一个二维表。

计算结果是二维表，可以继续进行排序、查询，或分组汇总等运算。
